Application of Permanent Magnet Bafe12o19 and Ndfeb on Small Scale Low Speed Permanent Magnet Generator

Abstract

Designing and manufacturing of low speed permanent magnet generator (PMG) for small scale electric power plant have been conducted. In this paper, the characteristics of generator using permanent magnet of barium ferit (BaFe12O19) and neodymium iron boron (NdFeB) were compared. Surface mounted type is selected as the rotor structure as all flux faces to stator winding and take a role in energy conversion. The experiment result demonstrates that at nominal speed, generator with BaFe12O19 magnet can only generate power of 8.87 W while generator with NdFeB magnet can generate power of 1,988.93 W
